They have a bunch of MANPADS, a handful of kubs/buks, and a single functioning battalion of S-300s (aka like 8 available missiles, not nearly enough). The MANPADS are worthless against high altitudes so can only be used against helicopters, the kubs/buks are too old to be relevant against modern ECM and stealth, and the S-300s are too few to provide meaningful defense as they can be easily targeted and don't have enough capacity to saturate air targets. Modern air defense is something only countries with money to burn can meaningfully do, either via their own stealth fighters or with so many advanced SAMs that it's impossible to do SEAD effectively.
